Can DVD Player Laser corrupt an SVCD Disk?

[EricB]

I have had two cases of SVCD disks starting to fail. These played perfectly several times and don't show any physical damage (scratches or fingerprints). They play along for a while, then produce large blocks and freeze. I can often play the sections before and after the problem area. After problem develops, disk will also fail on computer.

The player is working great with all other disks. Is it possible for the DVD laser to corrupt the data on a CD-R?

CD-Rs are Hi-Val 650MB and player is Pioneer 343. Anyone else see this problem?

Last try to get an answer? Anyone?

I never used Hi-Val nor Innovation CDRs. They are not good in quality (last long). I only use them (when they have rebate to final cost=$0) for burning a test CD. After seeing my final product worked, I then use a better quality CD for my final and archived.

I don't think the laser corrupt your data, but the head in the drive can cause the label to get bubble and that's it. Your data is stored on the otherside of the label (not the otherside of the CD). The label got protected by a thin plastic which made you think that you data was written on it (the plastic).

If you buy a bulk blanks CD, sometimes you see a clear plastic on the top. That's the one which cover on top of your data.

Hopes this answer your question. Goodluck

Your symptoms describe what happened to me when I burned at too high a speed. This is probably a combination of cheap CDR's, burning speed and possibly some form of corruption. I slowed my burning speed to 2x and havent' seem a hint of a problem since then.
